Google sharpens aim on mobile marketing with AdMob

SAN MATEO, Calif. 
Four years ago, Omar Hamoui was just another ineffectual entrepreneur trying to spruce up his resume in graduate school.

Now, he's poised to become Google Inc.'s newest weapon as the company aims to extend its dominance of online advertising from computers to mobile devices.

Google is buying Hamoui's expertise in a $750 million acquisition of AdMob, a network for ads on iPhones and similar gadgets. He launched the business while struggling to support his wife and children as a student at the University of Pennsylvania's Wharton School.

Hamoui, 32, changed his life by setting up a system for advertising on mobile devices. Though that sounds simple, it was a breakthrough because Hamoui's network got around stifling controls that wireless carriers had imposed on the content their customers could see on their phones. The crack that AdMob opened in the carriers' "walled gardens" made it easier for independent programmers to profit from applications planted on mobile phones.

"It took a lot of guts because (the carriers) were the gatekeepers of the industry," says Rich Wong, an AdMob investor and board member who is with Accel Partners. "Back then, it was sort of like if you said no to the Godfather. Bad things could happen."

More than a year after Hamoui ignited the fuse, Apple Inc. blew up the status quo with the June 2007 introduction of the iPhone - which created a platform for applications chosen by users.

That has spawned more than 100,000 mobile "apps" for doing everything from bird watching to cooking poultry. The revenue from AdMob's ad network is one of the main reasons application developers can give the programs away or just charge a few bucks.

"Omar was absolutely the tip of the spear in this mobile media revolution," says Jason Spero, general manager of AdMob's North America operations.

If Google's proposed acquisition is approved by the U.S. Federal Trade Commission, Hamoui thinks he and AdMob's 150 employees will be in an even better position to turn mobile phones into moneymaking magnets.

Google is banking on it.

Drawing upon the more than $20 billion in revenue that it generates from Internet ads, Google has been investing aggressively in mobile technology. The Internet search leader has developed a free software system, Android, that runs mobile devices and is experimenting with its own phone, called Nexus One, that could be sold directly to consumers.

Google believes explosive growth in mobile advertising will justify its spending. For now, the market remains relatively small, with U.S. mobile advertising revenue expected to reach $416 million this year, according to the research firm eMarketer Inc.

AdMob has delivered nearly 140 billion ads on mobile Web sites and applications since its inception. That has helped AdMob double its revenue this year after tripling it last year. Hamoui won't be more specific, leaving it to analysts to estimate that AdMob's revenue this year will range between $45 million and $60 million.

That's less revenue than Google generates in a day. Nevertheless, AdMob's early lead in mobile advertising could trouble antitrust regulators already concerned about Google's growing power. The Federal Trade Commission has asked for more information about the deal - a sign that regulators want to take a closer look at how it will affect competition in the mobile ad market, which is expected to quadruple in size during the next four years.
